Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a multi-cell downlink control information (MC-DCI) that indicates scheduling information for scheduling channels on multiple component carriers (CCs). The UE may transmit, to the network node, channel state information (CSI) feedback for a set of cells scheduled by the MC-DCI based at least in part on a radio resource control (RRC) configuration. Numerous other aspects are described.
Claims26
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a network node, a multi-cell downlink control information (MC-DCI) that indicates scheduling information for scheduling channels on a first component carrier (CC) and a second CC;
- and
- transmitting, to the network node, channel state information (CSI) feedback for a set of cells scheduled by the MC-DCI based at least in part on a radio resource control (RRC) configuration, wherein transmitting the CSI feedback comprises:
- transmitting a first rank indicator (RI) for the first CC, a second RI for the second CC, one or more of a precoding matrix indicator (PMI) or a channel quality indicator (CQI) associated with the first RI for the first CC, a PMI and a CQI associated with a second RI for the first CC, a PMI and a CQI associated with the second RI for the second CC, and a PMI and a CQI associated with a first RI for the second CC.
A method of wireless communication performed by a network node, comprising:
- transmitting, to a user equipment (UE), a multi-cell downlink control information (MC-DCI) that indicates scheduling information for scheduling channels on a first component carrier (CC) and a second CC;
- and
- receiving, from the UE, channel state information (CSI) feedback for a set of cells scheduled by the MC-DCI based at least in part on a radio resource control (RRC) configuration, wherein receiving the CSI feedback comprises:
- receiving a first rank indicator (RI) for the first CC, a second RI for the second CC, one or more of a precoding matrix indicator (PMI) or a channel quality indicator (CQI) associated with the first RI for the first CC, a PMI and a COI associated with a second RI for the first CC, a PMI and a CQI associated with the second RI for the second CC, and a PMI and a CQI associated with a first RI for the second CC.
An apparatus for wireless communication at a user equipment (UE), comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive, from a network node, a multi-cell downlink control information (MC-DCI) that indicates scheduling information for scheduling channels on a first component carrier (CC) and a second CC;
- and
- transmit, to the network node, channel state information (CSI) feedback for a set of cells scheduled by the MC-DCI based at least in part on a radio resource control (RRC) configuration, wherein the one or more processors, to transmit the CSI feedback, are configured to:
- transmit a first rank indicator (RI) for the first CC, a second RI for the second CC, one or more of a precoding matrix indicator (PMI) or a channel quality indicator (CQI) associated with the first RI for the first CC, a PMI and a CQI associated with the second RI for the first CC, a PMI and a CQI associated with the second RI for the second CC, and a PMI and a CQI associated with the first RI for the second CC.
An apparatus for wireless communication at a network node, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit, to a user equipment (UE), a multi-cell downlink control information (MC-DCI) that indicates scheduling information for scheduling channels on a first component carrier (CC) and a second CC;
- and
- receive, from the UE, channel state information (CSI) feedback for a set of cells scheduled by the MC-DCI based at least in part on a radio resource control (RRC) configuration, wherein the one or more processors, to receive the CSI feedback, are configured to:
- receive a first rank indicator (RI) for the first CC, a second RI for the second CC, one or more of a precoding matrix indicator (PMI) or a channel quality indicator (CQI) associated with the first RI for the first CC, a PMI and a CQI associated with a second RI for the first CC, a PMI and a CQI associated with the second RI for the second CC, and a PMI and a CQI associated with the first RI for the second CC.
